5.3 Ranges

In MacSlope, a Range is a defined distance through which circular slip surfaces must pass. It is a method of restricting the search to a particular area of interest, and can be used to target the critical factor of safety passing through a particular region of the slope geometry.

Select Define Range under the Analysis tab of the tool palette, and draw using the mouse inside the drawing bounds over the distance you wish to create the range.

MacSlope draws the extents of the range in green.

You will be presented with two blue markers representing the boundaries of the range.

Click a marker to edit the range boundary with text input.

Drag a marker to graphically move the range boundary. It will snap according to the snap preferences.

There are a maximum of 2 ranges per drawing.

Using the Select/Pan Tool to delete a range

Select the Select/Pan Tool in the Drawing tab of the tool palette, and click once on a range in the drawing to select it. The range will be highlighted to indicate it is selected. Now right click and a menu will be presented with the option to delete the range.
